Dear all
I created a Data Entry web page (PHP) that has a form with a number of components such as name, mobile , age, etc... (text fields). These data is entered in the database. This page is used by more than one user at a time.
The problem is that some records are entered twice or more in the database. There are some records was entered 15 times and all of them at the same time.
I am sure that my code execute the SQL statment once only.
What could be the problem? Why the script is executed more than one time?
Is it a Thread issue?
Is it a Server issue?
My database is Oracle and the page is in PHP.
regards

hi mhmo
you see, sometimes when we design our tables, we bare in mind that there might be two "john" or "Marry", so we need to identify them uniquely, we add an identity column or we look for something that will make them unique, like Social Security number, or ID number in your Country, but if you want to use that you can use IDentity column, by that you can track your problem, Another thing is that after your user submit your form that will insert data into the table, you have make sure that your user click it once. after a user click your Submit or save button once, Disable your button and display a Progress bar and you will have less Problems.
Hope this Helps

hi
I know that. And already I have an identity column and also I am disabling the button.
It seems that the problem is a Thread related or Server related.
Thanks

Hello,
I have executed a stored procedure written in SQL Server by calling it through VC++.
It was done through ODBC APIs SQLConnect(),SQLBindParameter(),SQLExecDirect() etc.
Now I want to pass parameters to the procedure I know the syntax that I am suppose to write in VC++.
But what changes should I make in the procedure in SQL Server.
I have the following stored procedure in SQL in which I want to accept 'LPG' and 'Mumbai' as parameters
CREATE PROCEDURE tryproc AS
SET @first = 0;
( SELECT SUM(t) AS first FROM demand WHERE product = 'LPG' AND LOCATION = 'Mumbai' )
create table abc (demandsum int);
insert into abc (demandsum) values (@first);
Is this the right forum to ask this question ?else direct me to the right forum.
Thanks

Hello All,
I am using SSRS 2005. I have problem on logon page, when cookie is not available. This should generate new cookie: But I am getting error and control returns.
I am getting following error: [System.NullReferenceException] = {"Object reference not set to an instance of an object."}
This comes with the 4th line of the code:
Following is the code:
internal static void RelayCookieToClient(Cookie cookie)
{
// add the cookie if not already in there
if (HttpContext.Current.Response.Cookies[cookie.Name] == null)
{
HttpContext.Current.Response.Cookies.Remove(cookie.Name);
}
HttpContext.Current.Response.SetCookie(TranslateCookie(cookie));
//HttpContext.Current.Response.AppendCookie(TranslateCookie(cookie));
}

There's 3 problems with your post.
1. Your title is too vague. Read the forum guidelines.
2. You haven't asked a specific question.
3. You've posted too much code. There's too much stuff to wade through. Again, identify what your problem specifically is and post only the code that is relevent.

I'm not really sure what the problem is. I can see that you have lifted the code from a Microsoft sample application though. In the Microsoft sample, they use SetCookie rather than AppendCookie. However I'm not sure whether this is significant.
Is the code actually falling over on this line, or it it failing in TranslateCookie?

hi
its Either your password is wrong , or you are Connecting to a wrong Server, that has no User that you want to Exit, remember that the useer does not roam, if you have create a user for a certain server , it will not work in other servers, i suggest you try to create a new user with the same name as the one you are saying, you have, if it says it exists, them the user does not exists in that server.
Hope it helps

Hello,
I am new to ADO and have to learn it for work so im playing aroud with it...my problem is that I have a blank datagrid on my form. I am trying to make a connection to an oracle database and create an SQL statement to retrieve the data I want and then display this in my datagrid...this is my code:
Dim dsWorkGroup As New DataSet 'New data set
'New connection string and variable to hold connection string ( i am sending the actual user name and password in the string)
Dim connectionString As String = "Data Source=PIDBDEV;User ID=######; Password=######;Unicode=True"
Dim connection1 As New OracleClient.OracleConnection(connectionString)
'Sql statement to retrieve the fields to fill the dataset
Dim selectStatement As String = "SELECT Group_Name FROM BASE_CALC_CODES"
Dim selectCommand As New OracleClient.OracleCommand(selectStatement, connection1)
Dim daWorkGroup As New OracleClient.OracleDataAdapter(selectCommand)
daWorkGroup.Fill(dsWorkGroup)
also I do have a datasourse attached to the datagrd. What am I doing wrong??? It isnt displaying the results from the query...it displays the entire table.

hi Erica
i have never connected to an Oracle DB, but now, you did not bind the datagrid to your dataset.
after the last line in your code, put the following line
Datagrid1.DataMember = "BASE_CALC_CODES"
Datagrid1.DataSource = dsWorkGroup
.
and i have an article, that has something like this, it might help you understand some of this and dont forget to vote.

Hello All,
First, I did try to search for the answer to this one and I either didn't use the correct keywords or something because the system didn't return any hits; so here I am.
Simply, I know there is a way to insert the same data into 2 different tables but I need to do it within 2 different databases. I am using a stored procedure but I am not sure how to set it up in the procedure. I know I need to enclose it in a transaction but how do I direct the insert to populate the second table in the other database?
Any assistance would be greatly enjoyed.
Fred
